If you don't understand why this doesn't work, then you probably don't
understand when this code runs. This code runs when the class is
loaded from users_controller.rb. In particular self is the class
UsersController, so you can't call authorize_admin? on it, since that
is an instance method and you don't have an instance of
UsersController.
In production this code only executes once (when the app starts), ie
there is no request or current user - clearly you can't be doing user
specific things at this point.
